Introduction to RM Compare

RM Compare uses Adaptive Comparative Judgement (ACJ), based on The Law of Comparative Judgement conceived by leading psychometrician L.L. Thurstone, which says that people are better at making comparative, paired judgements, over isolated evaluations.

The assessor (a teacher, lecturer, examiner or student) is presented with two anonymised pieces of work in a side-by-side pairwise comparison and asked to use their professional judgement to select which of the two is better at meeting the assessment criteria.

Through repeated pairwise comparisons, optimised by an iterative, adaptive algorithm, a highly reliable scale or rank order is created through consensus over what ‘good’, ‘better’ and ‘best’ looks like. Want a quick infographic explainer? It's as simple as A, B, Compare...

RM Compare enables users across educational organisations to collaborate on assessments wherever, however and whenever works for them and has been proven to increase student attainment.

RM Compare can help with:

“We see it as a great opportunity to help our students learn through evaluation – it turns the assessment process into a learning experience. The students collaborate with peers and with teachers to successfully improve their grades.”

“We found four big reasons why we believe adaptive comparative judgement is very successful for students.”

“Interestingly, the use of ACJ technology did not just benefit either the highest or lowest achieving students. It actually boosted the attainment of all the students who used RM Compare as a learning intervention.”

"RM Compare helps to boost the attainment of learners and improves the teacher’s judgements, as they have a clearer view of what good quality writing looks like, leading to better professional conversations between teachers at school."

Steve Dew, Headteacher
Church Cowley St James Primary School, Oxford, UK

“We are able to use this software to have more frequent assessments, across every year group and every child in the school. Which is different from the national assessment that we have to do for their writing, where everything comes to a head and at the very end of the year.”

“The process of moderation is designed to quality assure against things like bias in the traditional assessment setting. With this, there wouldn't be any need for that. It quality assures the judgements you're making by putting them against the judgements of many other teachers.”
